For those with the White Bros. E-Series exhaust

11 posts in this topic

I am curious to know what the average amount of plates are that everyone is using? I've been running 12 on my '00 WR400 but it's so dang loud that I pulled 7 out last night. I did quiet it down a good amount but I am conerned about the loss of power that I may have now. Any thoughts....

You will loss some top end power(not much IMO) but you will gain some in the bottom end. I run normally between 6 to 7 plates on my yz426, i am currently searching for a FMF Q to help quiet it down on the trails.

Im running the E-series, so adding plates increases top end, and taking them off adds bottom?

Nah, it's true. You enhance the bottom by giving the exhaust a smaller area to exit. Same concept the FMF Powerbomb headersuse; Powerbomb SX (smaller diameter headpipe) boosts the low end, Powerbomb MX (larger diameter headpipe) boosts the top end.

There are also differences in top and bottom power depending on which E-Series you run; ProMeg of S-Bend.

He is talking about the e-series with just the turndown endcap.

I ran that same setup except I made my own SA, and I lost about half my hp. It was weak. Last time I rode at StoneyFord ranger d!ck made me run 5 disks and my solid endplate and even like that I had to work to loft the front end. It makes best power with 10 disks, no solid end plate and a screen type SA. It does get loud, but I ride mostly private ground where there are no other riders but my bros....

speaking of the white bros. E-series exhaust. .. can you buy the screws at any local hardware store or doe they have to be ordered from white bros.?

You can get the screws local BUT remember to put "anti-seize" on them when they are installed. There should hav been a little white tube of it included with your silencer when it was new.
